A proportional relationship exists when the ratio between two quantities remains constant. This means for every increase in one quantity, there's a corresponding increase in the other quantity at a fixed rate.

The unit rate is a way of expressing a ratio with a denominator of 1. It tells you the amount of one quantity for each unit of the other quantity.

The constant of proportionality is the constant value that represents the relationship between two proportional quantities. It is the multiplier that relates the two quantities.

Percent change is the difference between the original and new value, expressed as a percentage of the original value. It indicates the relative increase or decrease.

Percent increase is a specific type of percent change where the new value is greater than the original value. It tells you how much bigger the new value is compared to the original.

Percent decrease is a specific type of percent change where the new value is less than the original value. It tells you how much smaller the new value is compared to the original.

The percentage change in a quantity when it increases from an initial value to a new value.

The percentage change in a quantity when it decreases from an initial value to a new value.
